Abstract: A battery management system, a battery pack, an electric vehicle and a battery charging time prediction method are provided. The battery management system includes a memory for storing a plurality of reference charging maps, a sensing unit for detecting voltage, current, and temperature of a battery, and a control unit for determining an estimated SOC value of the battery. Each reference charging map includes first to Mth reference current values and first to Mth reference power curves associated with first to Mth SOC sections. The control unit obtains a mth reference power curve and a mth reference current value associated with a mth SOC section to which the estimated SOC value belongs, from the reference charging map associated with the temperature section to which the temperature detection value of the battery belongs. The control unit determines the time required for the SOC of the battery to reach an end point of the mth SOC section, according to the result of comparing a maximum output power of a charger and the mth reference power curve, based on the difference between the end point of the mth SOC section and the estimated SOC value, and at least one of the mth reference current value, the maximum output power and the mth reference power curve.

Abstract: Disclosed is a battery, including: a housing having a cavity; a battery cell arranged in the cavity, the battery cell includes a positive electrode plate, a negative electrode plate, and a separator; and an electrolyte solution filled in the battery cell including fluoroethylene carbonate. A width of the separator is greater than that of the positive and the negative electrode plate. The battery satisfies following relationship: C≥B/20A+1, where a content of fluoroethylene carbonate in the electrolyte solution is C %, A represents a distance between an edge of the separator and that of an electrode plate on the same side, and B represents a height of the cavity. When the foregoing relationship is satisfied, deterioration of performance of the battery cell caused by insufficient electrolyte solution may be alleviated, thereby improving a value of a self-discharge coefficient k and cycling performance of the battery.

Abstract: An electrolyte solution for a sodium-ion secondary battery is described. By matching a first additive of a low-boiling-point sulfur-containing compound and a second additive of an oxalate-containing salt (a compound of formula (I)) and/or an oxalate ester (a compound of formula (II)) in the electrolyte solution, stable interface passive films are formed on a positive electrode and a negative electrode, such that the self-discharge rate and the cycling performance of the battery are improved, and meanwhile, the battery has a good power performance. The present application further relates to a sodium-ion secondary battery comprising the electrolyte solution, a battery module, a battery pack, and a power consuming device.
